So I bought Dayz Standalone awhile back, sometime last year. I downloaded it, and it was alright and stopped playing after while. I recently just redownloaded it, and I ran it as admin and veferity it before I loaded it up. I go to play and pick a server and get "Confirmation in Change Session lost." I try tons of servers and all give me the same issue. I heard where if you have a anti-virus it would cause a problem, which I did and so I uninstalled it. Restarted my computer and still same issue. I keep looking everywhere and I see where lots have this problem with no fix.. Someone out there Do you have a fix.. I tried everything I've seen out there

Ok thank you, seems like many have this damn issue..

Anyone know a fix? ;(
